Evidence Base
The Human Debt™ and Execution Integrity frameworks are grounded in observation, not theory.
Each category maps observed failure conditions to the dimensions they support. This page is the authority map. Applied case studies with full data are hosted at peoplenottech.com/research/field-evidence.
Technical Evidence
Hidden Execution Debt Inside SQL Server — Decoding the Statistics Blob
PeopleNotTech Research
Systematic mapping of the SQL Server statistics blob — the internal structure that governs query plans but is almost never directly inspected. Demonstrates that critical decision logic can be opaque even inside stable-appearing systems, and that this opacity accumulates as Execution Debt™.
Dimensions supported
- Inspectability
- Execution Drift Control
- Execution Debt™
Organisational Evidence
Novartis — Measuring and Growing Psychological Safety at Scale
PeopleNotTech × Novartis
7 teams, 4 months, 15 Plays. 76% of participants reported changing their behaviour. The pilot revealed a clear gap between perceived safety and actual data — teams used that dissonance as a lever for lasting change. Provides direct field evidence for the measurability and reducibility of Human Debt™ in enterprise environments.
Dimensions supported
- Human Verification Density
- Accountability Structures
- Human Debt™
FedEx — Building Psychological Safety, One Team at a Time
PeopleNotTech × FedEx
3 teams, 4 months, 5 Plays. 44% behaviour change. NPS 6.5. The biggest lever wasn't the software alone — it was giving teams permission and language to do the human work alongside operational work. Demonstrates that Human Debt™ is reducible with structured tooling in operational logistics environments.
Dimensions supported
- Human Verification Density
- Accountability Structures
- Human Debt™
AI Systems Evidence
Continuity-Governed Execution Infrastructure (CGEI)
Duena Blomstrom & Dave Ballantyne
Field research from inside accelerated AI execution environments. Human Debt™, Technical Debt™, and AI Execution Debt™ are converging into the same survivability problem. Documents the failure condition and the infrastructure layer required to prevent it — establishing the anchor theorem relating Human Verification Density, Correction Latency, and Accountability Structure Fidelity to Execution Integrity.
Dimensions supported
- Correction Latency
- Execution Drift Control
- Execution Survivability
- Human Verification Density
Structural Opacity in Institutional Systems
PeopleNotTech Research
A field analysis of black-box decision engines and the accumulation of Execution Debt™. Demonstrates how institutional failure begins with opacity — critical decisions governed by structures no one is looking at directly. Establishes the distinction between monitoring (observing outputs) and inspection (examining governing structure).
Dimensions supported
- Inspectability
- Execution Drift Control
- Accountability Structures
